PIANO-PEDAL.

To all whom it may concern:

Be it known that I, THOMAS H. DE Pnw, a citizen of the United States, residing at of Stark and State of hi0, have invented a new and useful Piano-Pedal, of which the following is a specification.

My invention relates to improvements in piano pedals in which a pedal shank is provided having a reduced outer end and a detachable ioot piece.

The objects of my invention are, first to provide a simple piano pedal; second, to provide a detachable foot piece; and third, to provide means for attaching the foot piece in such a manner that when attached a rigid connection is made. These objects, together with other objects readily apparent to those skilled in the art, may be attained by the construction illustrated in the accompanying drawings, although the invention may be embodied in other forms, the construction illustrated being chosen by way of example.

In the accompanying drawing: Figure 1 is a bottom or under side view of the shank and detachable foot pedal properly connected together. Fig. 2 is a section taken on line 2-2, Fig. 1. Fig. 3 is a side elevation of the foot pedal. Fig. 4 is an end view of the foot pedal. Fig. 5 is a detachable side view showing a portion of the pedal shank. Fig. 6 is an end view of the pedal shank.

Similar numerals of reference indicate corresponding parts in all the figures of the drawing.

In the accompanying drawing, 1 represents the pedal shank, the inner end of which is provided with the usual connecting pin 2. The outer end of the shank 1 is provided with the reduced portion 3, which reduced portion is provided with the undercut notch 4, the lip 5 constituting one wall of said notch is inclined downward and rearward as best illustrated in Fig. 5. The foot pedal 6 is hollowed out from its under face or side whereby a chamber 7 is provided. The foot pedal 6 is also provided with the socket 8, which socket is formed of a size and shape corresponding with the size and shape of the reduced extended portion 3. The foot pedal 6 is also provided with the rearwardly extendin plate 9, the rear end of which is provi ed with the open Specification of Letters Patent.

notch or recess 10, which open recess is for the purpose of receiving the headed stud 11, the plate 9 being located between the head and the bottom or under side of the pedal shank 1 as best illustrated in Fig. 2.

For the purpose of providing a rigid connection between the pedal shank 1 and the foot pedal 6 when the parts are brought into proper relative position, the bottom or under side of the plate 9 at its rear end is beveled as illustrated at 12, whereby the notched portion of the plate can be forced between the bottom or under side of the pedal 1 and the upper face of the head located upon the stud 11.

For the purpose of holding the foot pedal 6 the leaf-spring 13 is provided, said spring being attached to the outer end of the foot pedal 6 by means of the screw 14: or its equivalent. The spring 13 is provided with the hook 15, which hook is seated in the under-cut notch 4 as best illustrated in Fig. 2, said. hook being so formed that it will snugly fit upon the inclined lip. When it is desired to detach the foot pedal 6 from the pedal 1 the hooked end of the leafspring 13 is pressed downward, thereby disengaging the hook t'rom the under-cut notch 4, at which time the foot pedal 6 is free to be detached from the pedal 1. In order to provide means for entering a pry such as a screw driver or nail the spring-leaf 13 is provided with a recess 16, which recess presents a proper opening for the insertion of a screw driver or nail.

It is well understood that the foot pedal or foot piece of a pedal becomes tarnished and worn from use and presents thereby an unsightly and displeasing appearance. By providing means for detaching the foot piece from the shank the same can be easily polished or replated without the necessity of removing the pedal shank from the inner part of the piano.

It will be understood that by locating the stud 4 in the open slot the foot pedal will be held against lateral movement and vertical movement. The foot pedal is provided with the usual upward extended portion 17 and is located in the usual position.

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is:

1. In combination, a piano pedal shank having a reduced extension at its outer end provided with an under-cut notch on its under surface, a piano foot pedal provided with a rearward extending plate and a socket, the rearward end of said plate provided with a notch, a headed shank secured to the pedal shank, a leaf spring secured at one end in the hollowed-out portion adjacent the outer end of the foot pedal, its opposite end provided with a curved hook to receive the under-cut notch.

2. In combination, a piano pedal shank having a reduced extension at its outer end provided with an under-cut notch on its under surface, said shank having a headed stud on its under surface spaced inwardly from the notch, a foot pedal being hollowed out from its under face, and having a receiving socket for the reception of the extension, and a leaf spring secured at one end in the hollowed out portion adjacent the Copies of this patent may be obtained for five cents each, by addressing the outer end of the foot pedal, its other end being provided with a curved hook to engage the under-cut notch, said foot pedal being formed with an integral solid plate, disposed forwardly of the receiving socket to engage under the pedal shank to steady the foot pedal vertically, the solid extension at its forward extremity, being formed with an open ended recess, to receive the headed stud, to not only steady the foot pedal vertically, but to prevent lateral movement of the foot pedal.

In testimony that I claim the above, I have hereunto subscribed my name in the presence of two witnesses.

THOMAS H. DE PEVV.
